Zida zomwe zimagwiritsidwa ntchito potenthedwa zimaphatikizapo kwambiri silicon kwambiri - siyicor-romimium otenthetsera chitsulo, otenthetsedwa-chromium otenthetsedwa chitsulo
Silika wamkulu pa chitsulo: Silicon zomwe zili ndi 5-6%, ndipo kutentha kwake kumatha kukhala kokhazikika pafupifupi madigiri a 850. Ngakhale kuti mphamvu zake ndizochepa ndipo zimatha kungopanga zigawo zosagwirizana ndi mikate zokhala ndi mphamvu, nthawi zambiri zimagwiritsidwa ntchito pansi pa ntchentche yothina yosiyanasiyana chifukwa cha kukana kwake kwa oxida.
Kutentha kwamphamvu kwa aluminiyam; Ndibwino kuti pakhale mbale yothikirako yopanda kutentha, koma zinthu zamakina ndi osauka, ndipo chinthu cha aluminiyamu ndichosavuta kutsatsa kupanga slag.
Kutentha kwambiri kwa chromium Kutentha Kwambiri: Kutentha kosiyana kumatha kusinthidwa chifukwa cha kusintha kwa chromium. Chromium zomwe zili bwino ndi 26-30%, kutentha kwa kutentha kwa kutentha kumatha kufikira madigiri okwana 1000; Chromium zomwe zilipo ndi 32-36%, kutentha kwa kutentha kumatha kufikira madigiri 1150, ndikukhala ndi zinthu zapamwamba.
RQtsi4Mo Inaponya chitsulo: Ili ndi mitundu yopanda moto yojambulidwa ndi zinthu zabwino kwambiri zotentha kwambiri, zoyenera kugwiritsa ntchito kutentha kwa malo. Ili ndi 4% silicon ndi 4% molybdenum, ndipo kuwonjezera pa zinthu zoyatsira izi kumathandiza kwambiri kutentha kwambiri kolimbana ndi chitsulo.
Mwachidule, posankha zinthu zachiwiri-zolimba kutentha, mtundu woyenera uyenera kusankhidwa molingana ndi kutentha komwe kumachitika ndi zofunikira zina. Silicon yokwezeka itaponda chitsulo, kutentha kwamphamvu kwa ma celmium kumata chitsulo ndi ma vqtsi4mo
